Do you really gain a good bit of time back using one, and do they get rid of all the little 2-boat triangle note pad drawings next to my desk  ? If so, I think I may actually build one. |
Well, the way I use them they don't really save you much time, per se, as you have to take 2 observations of bearing and range. They do make the calculations easier, however, and obviate the need to make an actual drawing.
I highly recommend that you build at least the backside of Hitman's wheel. I've built three different whiz wheels (an old one from SHII days, the American SACF/IS-WAS, and the KM wheel). They work, and work well.
I've also built a couple of circular slide rules, and I often use a pocket sized linear slide rule (a commercial one, a Pickett N200-ES) for targeting. They all work on pretty much the same principle. I use the linear rule when playing on the sly. It's more discreet than the KM wheel.
But yes, it is worth it to build one and play with it.
